How you make n c thiner for auto paint?

To thin N/C (nitrocellulose) automotive paint, you can use a compatible thinner, such as nitrocellulose lacquer thinner or a specific paint reducer recommended by the manufacturer. Start by adding the thinner in small increments, typically around 10-20% of the paint volume, and mix thoroughly until you achieve the desired consistency for spraying. Always test the mixture on a small area or a sample surface to ensure proper flow and adhesion before applying it to the entire project.
